the advantages and disadvantages of traveling alone

In my point of view,the advantages of traveling alone is freedom and flexibility.You can see what you want,when you want it.The freedom of journeying alone makes everything so easy.There is no need to talk about the schedule with anyone else or to get a agreement on what everyone wants to do.
And I think there are two disadvantages of traveling alone.One is safety problem.Traveling with a team is more realistic when it comes topersonal security.The other is finance problem.When traveling alone,the expenses are all down to the individual,so if on a budget,dividing the expenses with another can be a better choice.
